A train packed with gold from nazis myth or reality?

  • Tunnel in Walbrzych, Poland, where it could be nazi treasures
 

As per the story, in 1945 a train packed with gold from the nazis disappeared when they tried to send it safe. The Polish authorities have got recent evidences that a train dated that time is buried in a tunnel along the current Poland and Czech Republic´s border, but in theory it only contains militar equipment. Would be true the legend?
